Sometimes when you visit a website and you see the website have some changes. But the website's functions are not working for you, because your web browser is caching the outdated website's resources: javascripts, stylesheets (css), images, etc...

What is Cache

Cache is a temporary storage that stores data in order to load user’s future requests for that data faster, so the next time users open it, the website / mobile app will be loaded much faster. With a website, your web browser will cache the website's resources such as: javascripts, stylesheets (css), images, and other media data...

What is the different between Cache and Cookies?

An HTTP cookie (also called web cookie, Internet cookie, browser cookie, or simply cookie) is a small piece of data sent from a website and stored on the user's computer by the user's web browser while the user is browsing. Cookies were designed to be a reliable mechanism for websites to remember stateful information (such as logging in, items added in the shopping cart in an online store). When you clear the cookies of an website, you will log out automatically.

So Cache and Cookies are different, when Cache is a temporary storage that stores the website resources such as: javascripts, stylesheets (css), images, and other media data. In some cases, you will need to clear both Cache and Cookies to make the website's functions working again.
